ABSTRACT OF THE DISCLOSURE A valve timing control device includes a rotatable shaft, a housing including a timing wheel axially immovable but angularly movable with respect to the rotatable shaft, a piston disposed coaxially with the rotatable shaft and the timing wheel, a hydraulic chamber for applying a hydraulic pressure to move the piston axially, a servovalve disposed between the hydraulic pressure chamber and hydraulic pressure supply and release passages and comprising a sleeve and a spool, an actua- tor for axially moving the spool, and a phase adjusting mechan- ism operatively coupling the piston, the housing, and the rota- table shaft for varying angular relationship between the timing wheel and the rotatable shaft in response to axial movement of the piston. The actuator may be a hydraulic actuator or an electric actuator. The phase adjusting mechanism may comprise roller pins mounted on the piston and rollingly fitted in a guide groove defined in the rotatable shaft and a guide slot defined in the housing, or meshing helical teeth on the piston, the housing, and the rotatable shaft.
